Short-circuit breaking capacity runs 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V — the steep drop above 500 V means you need to verify the available fault current at the point of installation if the system runs 690 V line-to-line; below that, the SCCR is generous enough for most industrial switchboards. Thermal derating is published per degree: full 400 A up to 50 °C, then 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C — if your panel ambient runs hot, that 340 A at 70 °C is the real continuous limit, not the 400 A nameplate. The basic switch is order code 3VA2340-6HL32-0AA0 — the -0CH0 suffix adds the UVR and aux-switch package, so if you already have a bare 3VA2340-6HL32-0AA0 in the panel and need the releases, this variant is a drop-in replacement with the same frame and trip unit. Dimensions are 248 mm high, 138 mm wide, 110 mm deep — the 138 mm width is the standard 3-pole MCCB footprint for this frame size, so it fits existing SENTRON 3VA mounting bases and bus-bar kits without panel rework.","metaTitle":"Siemens 3VA2340-6HL32-0CH0 SENTRON MCCB, 400 A, 600–4000 A t","metaDescription":"Siemens SENTRON 3VA2340-6HL32-0CH0 molded case circuit breaker, 400 A continuous, adjustable trip 600–4000 A, 242 kA at 240 V.
